An extensive series of catacomb-like tunnels or caverns exists beneath the surface of the Island. This article references those in the general area of the Barracks. These tunnels form part of an underground location used by the Others. Hieroglyphs adorn many of the pillars and walls throughout the Tunnels.

These tunnels link to similar ones beneath the Temple, a journey which would take a day and a half traveling above ground from the Barracks.

Entrances

The tunnels include at least three known entrances. One can be reached by diving into a stream out in the jungle and swimming in underneath a small waterfall. Richard indicates that there is another much larger entrance which was used to to bring the bomb into the tunnels. ("Follow the Leader") It appears the Hostiles may have deliberatedly bricked up some of the entrances. Richard uses a sledgehammer to break through one of the walls to provide access to the basement of Horace's house inside the Barracks compounds. ("The Incident, Part 1")

Jughead chamber

In a large chamber somewhere within the tunnel system underneath the Barracks is where the Hostiles hid the hydrogen bomb Jughead sometime after 1954. The bomb was placed here to contain continued radiation leakage. Like many other areas in the tunnels, there are hieroglyphs on many of the pillars within the chamber. ("The Incident, Part 1")

Trivia

An article "Enter: The Tunnels" from Lost: The Official Magazine indicates the 'declivity' in the Temple wall leads to another area of the Tunnels - suggesting that the tunnels beneath the Temple and those beneath the Barracks may be linked. [1]
